I'm sitting in a room at \(20^{\circ}C\) when all of a sudden it warms to \(40^{\circ}C\).
What is the percent change, to the nearest integer, in the temperature \(T\)?
Details & Assumptions:
- The formula for percent change between \(x_{1}\) and \(x_{2}\) is \(\Delta\)% \(= 100\large{\frac{x_{2}-x_{1}}{x_{1}}}\).
